Midkine Recombinant antibody

Midkine is a heparin-binding growth factor identified over 20 years ago and enhances the survival, migration and many other activities of target cells. Midkine is rich in both basic amino acids and cysteine, and is not related to most other growth factors/cytokines. It is strongly expressed during embryonic periods, especially at the midgestation stage, and plays important roles in development, especially in neurogenesis. Midkine expression in adult tissue is generally weak or undetectable, and it is induced upon injury and exerts many activities related to tissue repair. The biological activities of midkine in malignant tumors include proliferation, angiogenesis, invasion and metastasis. Various cancers express significantly higher levels of the midkine protein in early stage tumor tissues than in adjacent normal tissue.
